Fuel Efficiency Analysis
The Weichai WD615 engine platform, when paired with the HW19710 transmission and optimized gear mapping, delivers an average fuel consumption of 28–32 L/100 km under mixed operating conditions (60% loaded haul, 40% return/idle). In consistent 80% load cycles on graded haul roads (6–8% incline), fuel efficiency stabilizes at 30.5 L/100 km.
Key efficiency factors:
– Electronic Unit Pump (EUP) Fuel System: Enables precise injection timing and reduced parasitic losses.
– Optimized Gear Spacing: HW19710 allows engine to remain within torque peak (1,200–1,600 rpm) during ascent and descent.
– Lift Axle Engagement Logic: Center axle retracts when gross vehicle weight < 25T, reducing rolling resistance by ~12%.
Fleet operators report 12–15% lower fuel cost per ton-km compared to legacy 300 hp platforms in similar terrain.
Load Capacity & Payload Optimization
The tri-axle configuration with lift axle enables legal payload compliance across multiple regional regulations (China GB, GCC, and select African markets). Typical maximum payloads:
| Material Type | Density (kg/m³) | Max Volume (m³) | Approx. Payload (kg) |
|---|---|---|---|
| Crushed Limestone | 1,600 | 18 | 28,800 |
| Wet Sand | 1,920 | 15 | 28,800 |
| Asphalt Millings | 1,200 | 22 | 26,400 |
| Granular Fill | 1,800 | 16 | 28,800 |
Note: Maximum payload limited to 28.8–30.0 metric tons to remain within 40.5T GVWR and axle load limits. Overloading compromises brake performance and frame integrity.
Operational Recommendations
- Transmission Use: Utilize HW19710’s skip-shift capability (e.g., 4→6, 5→7) on graded return runs to maintain momentum and reduce shift cycles.
- Tire Maintenance: 12.00R20 tires require bi-weekly inflation checks (recommended pressure: 85 psi front, 90 psi drive). Off-road tread compound degrades 20% faster on paved haul roads—rotate axles every 8,000 km.
- Engine Service Interval: Oil and filter change every 10,000 km or 500 hours (whichever comes first). Use Weichai-recommended CI-4 15W-40 lubricant.
Conclusion
The Mack tri-axle dump truck with Weichai WD615 engine and HW19710 transmission delivers a balanced solution for high-intensity hauling with proven reliability in abrasive environments. Its 336–375 hp powerband, 40.5T GVWR, and optimized fuel economy make it a competitive asset for mid-to-large construction fleets seeking durability and cost-per-ton efficiency.
